Matrix-induced autologous chondrocyte implantation
Matrix-induced autologous chondrocyte implantation (MACI) is a two-stage cartilage repair technique in which a patient's own cultured chondrocytes are implanted on a collagen membrane, mainly for knee defects.
Measured resection
Measured resection is a total knee replacement technique in which fixed bone cuts are sized to the patient's anatomy and implant, then ligaments are balanced by release.
Meniscal repair
Meniscal repair is an arthroscopic knee procedure that sutures a torn meniscus in place rather than removing it, preserving load-sharing tissue and slowing joint degeneration.
Meniscectomy
Meniscectomy is a surgical procedure that removes part or all of a damaged knee meniscus, most often arthroscopically, to relieve pain and mechanical symptoms like locking.
Meniscus root repair
Meniscus root repair is an arthroscopic technique that reattaches a torn meniscal root to its tibial insertion, most often the medial meniscus posterior root, introduced in 2006.
Microdiscectomy
Microdiscectomy is a surgical procedure that removes herniated lumbar disc material pressing on spinal nerve roots, through a small incision with an operating microscope, to relieve leg pain.
Minimally invasive spine surgery
Minimally invasive spine surgery (MISS) is a family of techniques treating spinal disorders through small incisions and muscle-sparing corridors, reducing blood loss, complications, and hospital stay versus open surgery.
Mosaicplasty
Mosaicplasty is a surgical technique that repairs cartilage and bone defects, mainly in the knee and talus, by transplanting small plugs of healthy tissue from the same joint.
MPFL reconstruction
Medial patellofemoral ligament (MPFL) reconstruction is an orthopedic procedure rebuilding the ligament connecting the medial patella to the femur, typically with a tendon graft, to stabilize the kneecap after dislocation or recurrent instability.
Myelomeningocele repair
Myelomeningocele repair is the surgical closure of an open spinal birth defect, performed within days of birth or prenatally; prenatal repair reduces shunt-dependent hydrocephalus and improves early motor function.
Needle fasciotomy
Needle fasciotomy, also called needle aponeurotomy or percutaneous needle fasciotomy, is a minimally invasive hand procedure that divides Dupuytren's contracture cords with a hypodermic needle under local anesthesia.
Open Fracture Reduction
Open fracture reduction: surgical realignment of broken bone through a skin incision, usually with internal fixation (ORIF). Compared with closed reduction it offers more precise alignment but higher infection and nonunion rates in femoral shaft nailing.
Open reduction of fractures
Open reduction of fractures is a surgical procedure in which a fractured bone is exposed so fragments can be directly realigned, often combined with plate-and-screw internal fixation as ORIF.
Orthopaedic surgery
Orthopaedic surgery, the surgical specialty of the musculoskeletal system, supports a large journal ecosystem: 478 journals, impact factor trends, double-blind peer review, publication costs, and predatory-journal risks.
Orthopedics
Orthopedics is a peer-reviewed journal published by SLACK Incorporated since 1978 (ISSN 0147-7447), covering clinical orthopedic surgery; MEDLINE-indexed, 2025 impact factor 1.3, Scopus Q2.
Ostectomy
Ostectomy is a surgical operation that removes bone tissue, used in orthopedics to eliminate diseased or painfully contacting bone, and in periodontics to excise tooth-supporting alveolar bone.
Osteoplasty
Osteoplasty is a surgical procedure that reshapes, repairs, or grafts bone to restore skeletal structure and function, covering open bone grafting and percutaneous cement injection for painful lesions.
Osteosynthesis
Osteosynthesis is the surgical joining of broken bone fragments with implants such as plates, screws, intramedullary nails, or wires, holding them firmly in position while the fracture heals.
Osteotomy
An osteotomy is a surgical operation in which a bone is cut and realigned, such as the high tibial osteotomy for knee arthritis, to relieve pain and delay joint replacement.
Otto Sprengel
Otto Gerhard Carl Sprengel (1852–1915) was a German surgeon, head of surgery in Braunschweig, remembered for Sprengel's deformity of the scapula and a transverse abdominal incision.
Partial meniscectomy
Partial meniscectomy is an arthroscopic knee surgery that removes only the damaged portion of a torn meniscus, performed over 500,000 times a year in the United States.
Pedicle screw fixation
Pedicle screw fixation is a spinal instrumentation technique in which screws inserted through the pedicles, the strongest bony columns of the vertebrae, are connected by rods to stabilize the spine.
Pedicle Screws
Pedicle screws are bone screws placed through the pedicle of the vertebral arch to anchor rod constructs in spinal fusion; the gold standard for 3-column posterior fixation, first used by Roy-Camille in 1963, with very low complication rates and CBT screws as a less invasive alternative.
Pelvic osteotomy
A pelvic osteotomy is surgery that cuts and repositions pelvic bones to improve coverage of the femoral head in a dysplastic hip, most often by the Bernese periacetabular osteotomy in adults.
Percutaneous Diskectomy
Percutaneous diskectomy (percutaneous nucleotomy, Diskectomy Percutaneous MeSH D017587): posterolateral, outside-the-canal removal of herniated disc material; first described by Hijikata 1975, automated by Onik 1985, done under local anesthesia.
Percutaneous fixation
Percutaneous fixation is an orthopedic surgical technique that stabilizes fractures with screws, pins, or rods inserted through small skin incisions without opening the fracture site, sparing its blood supply.
Percutaneous pinning
Percutaneous pinning is a fracture fixation technique in which Kirschner wires are passed through the skin into bone under imaging guidance, without open exposure of the fracture site.
Periacetabular osteotomy
Periacetabular osteotomy (PAO) is a joint-preserving operation that cuts the pelvis around the acetabulum and repositions the socket to correct hip dysplasia and delay arthritis.
Plate fixation
Plate fixation is a surgical technique for treating fractures that uses a metal plate and screws to provide absolute or relative stability for bone healing.
Polycentric four-bar knee
A polycentric four-bar knee is a prosthetic knee joint for above-knee amputees in which a four-bar linkage replaces the single hinge, giving stance stability and better toe clearance.
